Newgrounds Wiki: Experience Points

Experience Points
Much like a traditional role playing game, registered users may acquire experience points and gain levels resulting in higher status. This is done by voting on five games and/or movies per day, which results in a deposit of ten experience points. You can only log ten points per day, there are no exceptions.

Experience points add weight to your votes. Users with an abundance of points will have the strength of multiple voters and can hurt the movies they hate or help the movies they love. Remember, you must be logged in for your voting power to be augmented!
